Abstract
Uranium in phosphate rock was removed by means of alkaline/leach solut ions. Ammonium carbonate/bicarbonate solution produced a very stable u ranyl carbonate compound which was separated by centrifugation. Radiom etric analysis showed that about 40% of uranium was solubilized and it can be recuperated. This process could be used before the manufacture of phosphatic fertilizers and the final products would contain smalle r uranium quantities.
